The point (7.8) in the coordinate plane represents a ratio. Adela caims that you can find an equivalent ratio by adding the same number to both coordinates of
the point is Adela correct? Explain.

1. a right triangle is graphed on a coordinate plane. find the length of the hypotenuse. round your answer to the nearest tenth. 2. use the angle relationship in the figure below to solve for the value of x. assume that lines a and b are parallel and line c is a transversal.

In the diagram, the ratio of ab to ae is (1/2) . what is the ratio of the length of to the length of ?

Iwill give ! if m∠a=59 and m∠3=81°, what is m∠b? m∠b= _[blank]_°
